Abstract: A delay circuit generates an output signal that changes state in adjustably delayed reponse to a state change in an input signal, the delay being adjusted by a control signal. A series of buffers (FDB1,..,FDBn) produces a plurality of delayed signals that change state at different times in response to state changes in the input signal. Amplifiers (A0̸,...,An) amplify the input and each delayed signal to pro­duce output currents that are summed to provide a load current through load resistors (R1, R2), thereby pro­viding the output voltage across the load resis­tors (R1, R2). The gain of each amplifier (A0̸,..., An) is adjusted in accordance with the control signal such that at least one and not more than two of the amplifiers (A0̸,..., An) have non-zero gain. The delay provided by the delay circuit is determined by the relative gains of the amplifiers.

Abstract: Air intakes (2), usually constituted by N.A.C.A. intakes, are formed in the sides (F) of the motor vehicle immediately in front of each rear light unit (1). When the vehicle is moving, each of the intakes (12) induces a flow of air towards the light unit (1). As it passes through flow-conditioning means, such as a deflector element (4) mounted in a corner position on the light unit (1) or a slot-like duct which passes through the light unit, this flow is transformed into a turbulent air flow. As it spreads into the space surrounding the surface of the light unit (1) and/or flows over it, this air flow prevents the deposition of dirt on the light unit.
